BlockIntegrations
With BlockIntegrations, I turn small block structures into useful machines. Players can build helpers for moving and sorting items, upgrade their furnaces, or add towers to defend a base against hostile mobs.

Features

• Inventory sorting plates, item vacuums and directional launchers.
• Sprint boosters, float lifts and healing blocks.
• Seven attack tower types with target profiles, redstone controls, loot storage and kill XP.
• Upgrades for furnaces, blast furnaces and smokers: speed, fuel use, yield, batch size and stored XP.
• Portable main blocks that keep their upgrade levels when broken and placed again.
• In-game building guides, with optional Core web and client views.

Requirements
Java 25, Paper/Purpur 1.21.8 or newer and Vystorm Core. Core 0.28.1 is included in the download. No client mod or database is required. VystormSkills is optional.

Installation
Stop the server and back up your plugin data. Extract BlockIntegrations-2.21.3-26.2.jar and the included Core dependency into plugins/. If you already use a newer Core, keep it instead of installing the bundled copy. Keep one JAR per plugin.
Start once to create the config, adjust the settings, then restart. Try your machines and protection settings on a test copy first. Do not hot-reload.

Commands and permissions
Start with /blockintegrations for the plugin's guides and controls. COMMANDS.md in the download lists the command arguments and permission defaults. English and German messages are included.

Updating an existing setup

• YAML data from before 2.20.2 is not imported automatically.
• Do not downgrade after saving towers in the newer format.
• Machine state is stored in local JSON files; there is no database to set up.
• Skills XP needs VystormSkills. Web and client views need their corresponding Core features.

Screenshots

Support and license
If a machine does not work as expected, post in the discussion with your server, Core and BlockIntegrations versions. Include how you built it and what happened; a screenshot often helps. Please remove private details from logs.
